High cycle fatigue simulations could be analyzed by professional and customized software like FE-safe software. However, in some cases, researchers and engineers prefer to use unique software for finite element analysis and fatigue calculations Ir to use specific equations based on new theories in fatigue calculations, while these are not equations in the software. In this case, you can use Subroutine by FORTRAN language or Scripting by PYTHON language for fatigue implementation and computation.
